Payments can be made with PayPal or Bitcoin. To keep prices as low as possible, Bitcoin is a wonderful alternative and is growing in popularity daily! Bitcoin is a decentralized currency, i.e. there's no banking fees especially with International transfers (how nice!). Bitcoin is easy to purchase at your local bank with cash, credit or debit card at Wall of Coins. Also, LocalBitcoins and Coinbase are nice options.
If you have questions, let me know.
